Which of the following sequences correctly represents the flow of electrons during photosynthesis?

True or false- Oxygen is produced during the Calvin cycle?

Plants are photoautotrophs. What does this mean?

They are among the producers of the biosphere. They make their own food from inorganic materials. They are in the same category as algae and cyanobacteria. They use light energy to drive the synthesis of organic molecules

Define heterotrophic

What is the role of redox reactions in photosynthesis?

H2O is split, electrons are transferred along with hydrogen ions from H2o to CO2, reducing it to sugar. Electrons increase in potential energy as they move from H2o to C6H12O6, this process requires energy (endergonic). Energy boosts are provided by light

Explain the function of cyclic electron flow.

Describe the similarities in chemiosmosis between oxidative phosphorylation in mitochondria and photophosphorylation in chloroplasts.

Electron transport chain in membrane pumps protons across membrane, electrons are passed through a series of carriers (progressively more electronegative) ETC transform redox energy to a proton-motive force, potential energy stored as H+ gradient across a membrane. ATP synthase complex- diffuse H+ ions down their gradient to the phosphorylation of ADP.
